hi there.
recently sony has launched new firmware i.e 10.1.1.A.1.253...
i was thinking to update my phone but i thought to make a backup of stock firmware...
so here is the question->
if i update my phone and the new firmware is not so good and if i want to revert back to my old firmware can i do so and if i can ,can i still update using sony companion and also if yes in the previous context can you please tell me how to backup firmware...
it stuck me because in samsung phones once you update via kies to a firmware and you revert back(maybe using flashtool) to stock firmware then you are not able to update
via samsung kies...
my current firmware:10.1.A.1.434
thanks for looking in...
